Algae: Protists with Chloroplasts The algae are a polyphyletic and paraphyletic group of organisms. They are defined in differing ways, but are usually considered to be the photosynthetic organisms excepting plants. Using the term 'plants' in its most restrictive fashion, the algae are then photosynthetic organisms excepting the sister group to the Charales (i.e. the land plants). Such a definition allows inclusion of photosynthetic prokaryotes such as the cyanobacteria.

Green algae The green algae (singular: green alga) are a large, informal grouping of algae consisting of the Chlorophyte and Charophyte algae, which are now placed in separate Divisions. The land plants or Embryophytes (higher plants) are thought to have emerged from the Charophytes.here are about 8,000 species of green algae. Many species live most of their lives as single cells, while other species form coenobia (colonies), long filaments, or highly differentiated macroscopic seaweeds. A few other organisms rely on green algae to conduct photosynthesis for them.

Algae description and types The algae have chlorophyll and can manufacture their own food through the process of photosynthesis. Recently they are classified in the kingdom of protiste, which comprise a variety of unicellular and some simple multinuclear and multicellular eukaryotic organisms that have cells with a membrane-bound nucleus.

Alternation of generations In those algae which have alternation of generations, the sporophyte and gametophyte are separate independent organisms, which may or may not have a similar appearance. In liverworts, mosses and hornworts, the sporophyte is less well developed than the gametophyte and is largely dependent on it.

Difference between Bacteria and Algae Algae are simple Eukaryotic photosynthetic autotrophs. They can be unicellular as well as multi-cellular. They belong to the kingdom Protista. Due to the presence of chlorophyll, Algae are capable of making their own food and the process is referred to as photosynthesis. Most of them are microscopic. However, few are quite large and can exceed in meters lengthwise.

Algae, Phytoplankton and Chlorophyll Algae are aquatic, plant-like organisms. They encompass a variety of simple structures, from single-celled phytoplankton floating in the water, to large seaweeds (macroalgae) attached to the ocean floor 2. Algae can be found residing in oceans, lakes, rivers, ponds and even in snow, anywhere on Earth.

- If you’re hoping that the gut-punch of a reveal that took place in Tuesday’s Pretty Little Liars summer finale was yet another of the series’ misleading twists, you’re out of luck.Turns out, the addictive ABC Family drama plans to stick with (to some degree) the shocking notion that — SPOILER ALERT — Ezra is ‘A’!or people that don’t want Ezra to be A because he’s Aria’s love interest, you do realize that if one of the good ones isn’t A, all’s left is someone that’s already bad (Melissa, Shauna, Jenna, etc), someone we don’t really care about (Wren, Noel, etc) or Ali. That’s freaking boring.

- Types of Protists A. Plantlike Protists 1. algae = single-celled and many-celled plantlike protists. a. All algae contain chlorophyll in chloroplasts and make their own food (they are producers). b. The algae may also contain other pigments (colors) in addition to chlorophyll, giving them a color other than green.

Algae, Phytoplankton and Chlorophyll Photoreceptors absorb light energy, and chlorophyll specifically absorbs energy from sunlight 15. Chlorophyll makes plants and algae appear green because it reflects the green wavelengths found in sunlight, while absorbing all other colors. However, chlorophyll is not actually a single molecule.hile algae contain chlorophyll (like plants), they do not have these specialized structures 8. Algae are sometimes considered protists, while other times they are classified as plants or choromists. Phytoplankton are made up of single-celled algae and cyanobacteria.

- The algae are simple photosynthetic plants that live in water. Most species are small to very tiny; many can only be seen with a microscope and often float or swim as plankton in the water column. But some algae--what we often call pond scum or seaweed--are conspicuous plants that can form dense mats of vegetation.pecial commercial products of algae. Profitable products can be extracted from algae. There are four major algal products, and all four are extracted from the cell walls of the organism. 1  Agar.

- The third and fourth groups of protists, the algae, contain chloroplasts and photosynthesize like plants; these can be unicellular, colonial, or multicellular. Multicellular marine algae, the seaweeds, are similar to marine plants, and many biologists support moving seaweed into the plant kingdom.

Wetland There are three main groups of algae: 1  Plankton are algae which are microscopic, free-floating algae. This algae is so tiny that on average, if 50 of these microscopic algae were lined up end-to-end, it would only measure one millimetre. 2  Filamentous algae are long strands of algae cells that form floating mats.

- The plant-like protists are commonly referred to as algae and can be either single-or multi-celled. Algae contain chlorophyll and carry out the process of photosynthesis. Diatoms are single-celled algae that excrete a cell wall made of silica.ingdom Protista contains the protists, or all the organisms that do not fit into the other kingdoms of life. Protists can be heterotrophic or autotrophic, mobile or immobile, single-celled or multi-celled, solo or a member of a colony. They are categorized into three main categories based on how they obtain nutrients.

Microbes and the World Algae, also called cyanobacteria or blue-green algae, are unicellular or multicellular eukaryotes that obtain nourishment by photosynthesis. They live in water, damp soil, and rocks and produce oxygen and carbohydrates used by other organisms. It is believed that cyanobacteria are the origins of green land plants.

Green algae Green algae are eukaryotic organisms that follow a reproduction cycle called alternation of generations. Reproduction varies from fusion of identical cells to fertilization of a large non-motile cell by a smaller motile one . However, these traits show some variation, most notably among the basal green algae called prasinophytes.

Green algae The green algae include unicellular and colonial flagellates, most with two flagella per cell, as well as various colonial, coccoid and filamentous forms, and macroscopic, multicellular seaweeds. In the Charales, the closest relatives of higher plants, full cellular differentiation of tissues occurs.There are about 8,000 species of green algae. Many species live most of their lives as single cells, while other species form coenobia (colonies), long filaments, or highly differentiated macroscopic seaweeds.A few other organisms rely on green algae to conduct photosynthesis for them.n the Charales, the closest relatives of higher plants, full cellular differentiation of tissues occurs.

- ALGAE: These water-loving eukaryotes can range in size from microscopic, single-celled organisms to giant kelp. Algae are more plant-like than animal-like, in that they make their own food from carbon and sunlight energy (photosynthesize). Most algae are beneficial, even critical for life on earth. Few cause disease.

Algae, Phytoplankton and Chlorophyll While algae contain chlorophyll (like plants), they do not have these specialized structures 8. Algae are sometimes considered protists, while other times they are classified as plants or choromists. Phytoplankton are made up of single-celled algae and cyanobacteria.ulticellular green algae is also not considered phytoplankton for the same reasons. To be considered a phytoplankton, the algae needs to use chlorophyll A in photosynthesis, be single-celled or colonial (a group of single-cells), and live and die floating in the water, not attached to any substrate 1.
